"The chances of at least 410 amino acids accidentally forming a chain to produce one protein molecule is 10123. The odds against this happening in at least 239 protein molecules to form the smallest living organism are 1029345. The odds of that one organism surviving long enough to learn to eat, breathe and reproduce are beyond calculation."

I don't know from where you get your probability calculations, but assuming they are correct, if these processes occured millions and millions of times, one would get 410 amino acids forming a protein molecule fairly quickly and easily. Same with forming the smallest organism.
